Specification of Letters Patent.

Patented Apr.11-, 1916.

Application filed August 13, 1915. Serial No. 45,365.

To all whom. it may concern Be it known that I, SILVIO F Avno, a subjectof Victor Emmanuel III, King of Italy, residing at Pocatello, in thecounty of Bannock and State of Idaho, have invented a new and usefulMacaroni-Drier, of which the following is a specification.

The present invention is an apparatus adapted for drying macaroni andkindred commodities or articles, and aims to provide a novel andimproved device of that character.

It is the object of the invention to provide a macaroni drier comprisinga casing having means therein for supporting the macaroni, and means forestablishing the circulation of air around the macaroni for properlydrying the same.

The invention also includes unique means for controlling the circulationof air and ventilation of the drier, whereby the desired results may beobtained in a satisfactory manner.

It is also within the scope of the invention to provide a dryingapparatus of the nature indicated which is comparatively simple andinexpensive in construction, as well as being convenient, practical andeflicient in use.-

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and details of construction hereinafter describedand claimed, it being understood that changes in the precise embodimentof the invention herein disclosed can be made within the scope of whatis claimed without departing from the spirit of the invention. V

. The invention is illustrated in the accompanying drawings, whereinFigure 1 is a front elevation of the structure. Fig. 2 is a verticalsection thereof taken on the line 22 of Fig. 3. Fig. 3 is a horizontalsection taken on the line 3--3 of Fig. 2. Fig. 4 is a vertical sectiontaken on the line H of Fig. 1.

In carrying out the invention, there is provided a casing 1 constructedof sheet metal or other suitable material, having a suitable framework,and the casing is provided therein with a pair of spaced parallelpartitions 2 providing end macaroni compartments or chambers 3 adjacentthe ends 4 of the casing, or between said ends and the partitions. Thepartitions are attached to the front and back walls of the casing, and

to the top and bottom thereof, and the partitions provide a central fancompartment or chamber 5 therebetween, and between the compartments 3.

The .macaroni is suspended within the compartments 3, and to this endvertically spaced pairs of cleats 6 are secured to the sides of thecompartments 3, formed by the partitions and the ends 4 of the casing,so

that the cleats 6 extend from the back wall of the casing to the frontwall thereof. The upper edges of the cleats 6 are notched for thereception of cross rods 7 upon which the macaroni is placed, so as to besuspended therefrom. The front wall of the casing is provided with twoupright door openings 8 for and co -extensive with the compartments 3,and upright doors 9 are normally disposed in the openings 8 and hinged,as at 10, to the casing to swing about'vertical axes to and from theopenings 8. The lower ends of the doors 9 extend to the lower ends ofthe openings 8, butthe upper ends of said doors are spaced from theupper ends of said openings, and the upper portions of said openings arenormally closed by depending doors 11 hingedly connected, as at 12, tothe top of the casing. The doors .9 and 11 normally close the openings8, the doors 9 being large enough, so that when theyare opened, theattendant or operator may. readily pass through the openings 8 p for.placing. the macaroni within the compartments 3.

The front wall ofthe casing" is provided with a central upright 'dooropening 13 between the openings 8 and co-extensive with the fancompartment 5. The opening 13 is normally closed by an upright door 14co-extensive with the opening 13 and hinged, as at 14 at one edge to thefront wall of the casing for mounting the door 14 for movement about avertical axis to and from the opening 13. The door 14, when opened,

permits the attendant or operator to enter the fan compartment 5 forattending to the fan, or the like. The door 14 has a window ortransparent panel15 therein whereby the attendant may observe theoperation of the fan from the outside, to determine the speed of the fanwithout the necessity of opening the casing. Each of the front doors 9and 14 is provided adjacent its lower end with a ventilating opening 16,in which. a

ventilating door or valve 17 is hung by means of hinges 18 fastened tothe respective door 9 or 14. The valves 17 swing by gravity into theopenings 16, and swing open outwardly.

It will be seen that the front wall of the casing is in the form of aframework, embodying three door frames for the doors 9 and 14. A fan 19driven by an electric motor or other actuating means is suspended withinthe fan compartment from the top or ceiling of the casing, and whenoperated produces a downward flow of the air within the partitions 2above the respective openings. The lower valves 22 swing open into thecompartments 3, and the upper valves 23 swing open into the compartment5, following the course of the air from one compartment to another. Theends 4 of the casing are also provided with ventilating means, and tothis end, each end wall of the casing is provided with a lower opening25 adjacent the bottom of the casing, and with an upper opening 26adjacent the top of the casing. Valves 27 and 28 are hung within therespective openings 25 and 26, and are hinged, as at 29, to the endwalls of the casing immediately above the respective openings. Thevalves 27 swing open inwardly. The openings 20, 21, 25 and 26 areelongated and extend horizontally between the back and front walls ofthe easing, and the valves for said openings normally tend to gravitateor swing downwardly for closing the openings. The top of the casing 1 isprovided with a hinged door 30, which when opened, provides an upper airinlet opening for the compartment 5. The door valve 30 may be swung openupwardly, and held open in any suitable manner, and the valves or doors17, 22, 23, 27 and 28 may also be held open to the desired extents inany suitable manner.

Adjustable ventilating shutters are pro vided in the upper portions ofthe compartments 3, above the macaroni supporting rods 7, andimmediately below the openings 21 and 26, and to this end, a pair ofcleats 31 is secured to the sides of each compartment 3 immediatelybelow the respective openings 21 and 26. A transverse series of slats orstrips 32 are terminally seated upon each pair of cleats 31, and may bespaced apart more or less for regulating the flow of air within therespective compartment It is an easy matter to'insert and remove theslats 32 by simply opening the doors 11, which swing outwardly, and theslats 32 may be arranged by hand for regulating the upward current ofair within the macaroni compartments, to suit the various stages ofdrying.

In operation, the macaroni may be readily placed within the compartmentsor chambers 3 when the doors 9 are opened, the macaroni being carriedupon the rods or sticks 7 which may be conveniently placed upon thecleats 6 within the macaroni compartments. The doors 9 are then closed,and the fan 19 is started. The fan creates upon the cleats 6 within themacaroni compartment 5, and the air will passthrough the openings 20,swinging the valves 22 open, so that the air will pass upwardly withinthe compartments 3 around the macaroni. The air returns from thecompartments 3 into the compartment 5 by way of' the openings 21, thevalves 23 being swung open into the compartment 5 to allow the air topass. Thus, during the operation of the fan, the air continually flowsdownwardly within the compartment 5 and up wardly within thecompartments 3, and the air encountering the macaroni will dry the Same.The valves or doors 27 and 28 may also be opened, either by the suctionof the air within the casing created by the fan, or manually, forallowing the proper ventilation of the casing according to the variousstages of drying. The doors or valves 27 and 28 may also be opened forallowing a natural draft through the macaroni compartments 3 when thefan 19 is idle or stopped. The door 30 can be opened when the fan is inoperation to allow fresh air to be drawn downwardly into the compartment5, and the valves or doors 17 may also be swung open for purpose ofventilation. The air controlling slats 32 may also be adjusted forcontrolling the upward flow of air within the compartments 3, and bymeans of the various controlling devices, the ventilation and aircurrents may be properly controlled to carry out the drying processsatisfactorily.

The device may be constructed on a larger scale, by providing moremacaroni compartments 3, if a larger capacity is desired, and otherchanges in details can be made, within the scope of what is claimed,without departing from the spirit of the invention.

' A hygrometer 33 is disposed in the chamber 5 to indicate the amount ofmoisture in the air, whereby the valves may be regulated properly. Thevalves may be regulated by chains or other suitable fixtures, and may bearranged to swing in either direction, in or out. The direction of theflow of air may be changed by reversing the fan, and 139 the door orvalve 30 may be used either for receiving fresh air or for an airoutlet. The end valves 27 and 28 and openings controlled thereby .areessential when a plurality of compartments 3 are used, but can beomitted when a single compartment 3 is employed. The ventilating meansat the ends may be or may not be used, according to the circumstances.

Having thus described the invention, what is claimed as new is:

1. A drying apparatus comprising a casing having a partition thereinprovided with upper and lower openings, the partition providing dryingand fan compartments, a fan within the fan compartment for creating acirculation of air through the compartments, and circulation controllingmeans within the upper portion of the drying compartment immediatelybelow the upper opening.
